[Intel-gfx] [PATCH V2 0/5] drm/i915/gt: Initialize unused MOCS entries to L3_WB

[Ayaz A Siddiqui]

Gen >= 12 onwards MOCS table doesn't have a setting for PTE
so I915_MOCS_PTE is not a valid index and it will have different
MOCS values based on the platform.

To detect these kinds of misprogramming, all the unspecified and
reserved MOCS indexes are set to WB_L3.

This series also contains patches to program BLIT_CCTL and
CMD_CCTL registers to UC.

Since we are quite late to update MOCS table for TGL so added
a new MOCS table for ADL family.

V2:
  1. Added CMD_CCTL to GUC regset list so that it can be restored
     after engine reset.
  2. Checkpatch warning removal.
